Answer 1

好吧，试试这个：

var query = from row in context.pageStat
            where row.UserName == "name"
            group row by row.PageName into g
            select new { PageName = g.Key, Count = g.Count() };

Answer 2

    var retVal = (from s in dataContext.YourTable where

s.UserName.Equals("name")
group s by s.PageName into k
select new {PageName = k.Key, Count = k.Count() }).ToList();
